FABRIC CONNECTION.

Application filed June 8, 1911.

To all whom it may concern Be it known that 1, CHARLES A. HANSEN, acitizen of the United States, and a resident of Elizabeth, Union county,New Jersey, have invented a new, useful, and Improved Fabric Connection,of which the following is a specification.

My invention relates to the art of sewing fabrics and its object is toproduce a new and improved connection for securing fabrics together.

One of the embodiments of my invention is illustrated in theaccompanying drawings in which Figure 1 shows in plan view theclothplate of a sewing machine and one form of attachment by which thefabric connection of my invention may be produced. Fig. 2 is a verticalsection of the cloth plate of Fig. 1 showing the needle and the presserfoot of the machine as well as the attachment in side elevation. Fig. 3is an end view of the device looking in the direction of the arrow atthe right of Fig. 2. Fig. 4 is a section of the device on the line 4-4:of Fig. 2. Fig. 5

is a section of the device on the line 5-5 of Fig. 2. Fig. 6 is alongitudinal section of the device showing one of the folders thereof inside elevation. Fig. 7 is a plan view of two fabrics and my improvedconnection therefor, as they are disposed immediately after the sewingprocess. Fig. 8 is an enlarged cross-section of the fabrics as shown inFig. 7. Fig. 9 is a plan view of the fabrics shown in Fig. 7 after theyhave been relatively moved into the same Plane and pulled apart- Fig. 10is a section similar to that of Fig. 8, but with the fabrics moved intoa common plane. Fig. 11 is a section similar to that of Fig. 10, withthe fabrics pulled apart and showing the lower surfaces of the fabricsand the connection in perspective. Fig. 12 is a longitudinal section ofthe edge-portions of the fabrics disposed as shown in Figs. 7 and 8,showing the manner of stitching.

A form of attachment by the use of which my fabric connection may bemade is illustrated by Figs. 1-6 inclusive.

The reference character 1 indicates the cloth plate of a sewing machineof any suitable type. For producing the particular fabric connectionshown by Figs. 7-12 inclusive, I may use the VVilcoX & Gibbs automaticsewing machine adapted to make loose Specification of Letters Patent.

stitches of constant length. I do not wish to be limited, however, tothis particular mach ine, but desire it to be understood thatmyinvention contemplates the use of any machine suitable for use in theproduction of a fabric connection set forth in the claims. Thecharacters 2 and 3 in Fig. 2 indicate the needle and the presser footrespectively of the sewing machine. Adjustably secured to the clothplate 1 and in position to discharge the fabric edge portions, properlyfolded, 1nto position to be pierced by the needle is the attachmentpreviously referred to, said attachment comprising two folders 4: and 4tsoldered or otherwise suitably secured to a base plate 5, which in turnis secured to a bracket 6, adjustably held on the cloth plate by theengagement with the walls of an elongated slot therein of a set screw 7,screwthreaded into the cloth plate. The base plate 5 is substantiallytriangular in shape and is set with one edge abutting the top of thecloth plate, the pointed end being near the needle. Secured along theconverging edges of this plate are the folders 4 and 4-, the feed endsthereof being spaced apart to a greater extent than the discharge endsthereof and said discharge ends being close together and near themachine needle so that the folded fabric discharging from one folderwill be above and in near relation to that discharging from the otherfolder and the folds will be pierced by the needle before their relativepositions are disturbed. Each folder is similar in conformation to itsassociated folder except that the convolutions and surfaces of the oneextend in directions opposite to those of the other. One may be said tobe a right-handed folder while the other is left-handed. A descriptionof the one, as will be readily understood, is applicable also to theother. Each folder is preferably formed from a sheet-metal plate bybending. Theplate is first bent in the region of the line 8, to form atthe feed end two guide walls for the reception of the fabric to beoperated upon, these walls being extended near said end to form wings 9.The walls are substantially parallel and near the base plate 5 they arebent or bulged outwardly to form an exterior convex surthe foldersubstantially into the forrn ofa. {the folded edge portion of one abovethe spiral of gradually decreasing diameter.

The inner wall of the two guide walls is cut away so as to present anedge 10, (Figs. 3, 5 and 6), this edge extending longitudinally towardthe discharge end of the folder and cutting across the region 8 near theline H of Fig. 2, which region now continues its path toward saiddischarge-end inthe form of an edge l.v The base plate is curved, aswill clearly be understood, t0v

conform to the variation'in diameter of the spiral portion, formed inthe manner described. The region 8 at the feed end'of "the folderis incontact with the base plate" 5. At the linei5 5 of Fig.2, as will beseen by an inspection of Fig. 5, it is at a distance I Fig. 2,-it hasmerged'into the edge 10,

shown in Fig. l. 'lhe spiral conformation of the portions describedserve partially to 7 turn over' upon the face of the fabric thefabric'edge-portion which is fed between the guide walls near the region8'thereof.- The outer guide wall is'not cut away as was the;

- inner wall, but is provided with an extension 11 near the dischargeend of the folder,

' which, is folded over, externally of the 'spirally-conformed portionpreviously de--- scribed, substantially into the form of a spiral ofgraduallydecreasing diameter, the direction ofthe last-mentioned spiralbeing opposite to that. of the first-mentioned spiral. The end ofthelspiral, formed'by the 5 bending of the extension ll, nearest to thefeed end of the folder-is marked by the substantially spiral edge 12 ofsaidextension;

which; edge as it approaches the discharge end gradually merges into thelongitudinal edge 12. As the fabric is fed from the feed end toward-thedischarge end of the folder,

while the edge portion thereof is being turned over by the portion 8 aspreviously set forth to formthe fold 13, a portion of therfabric at adistance from the edge, is

engaged by the spiral edge 12'and the spiral convolutions 'oftheextension 11, which pro duce a fold 14 in the fabric and turn said fold14 over and upon the oppositely turned fold 18,'thus forming a fold 15.-Upon dis- 1 charging from the device therefore the fabric has threesuperposed folds, the first due to theconvolution of theportion 8, thesecthe spiral convolution of the extension 11, so.

as to turn the second fold over-anduponthe first fold. Two of thesefolds, as will be 0nd due to the engagement of the spiral edge 12 withthe fabric, and the third due to seen, face in one direction While thethird faces in the opposite direction. Since the deviceillustratedcomprises two folders, one being oppositely convoluted withrespect to the other, when a fabric is fed into each folder, saidfabrics are folded over in the manner described and" are discharged withoppositely folded edge portion of the other.

Thuspositioned,they are pierced by the needle and secured together asthey move along, by a loose stitching, leaving the sewing machinesecured together and disposed V as shown by Figs. 7 and 8. The fabricsare relatively rotated about the secured edge portions into a commonplane as shown by Fig. 10. The folds are now loosely held and are notnecessarily closely associated. Upon pulling the fabrics apart, thefolds, as will be apparent,,are moved into close relationship, as shownin Figs. 9 andll. The upper surfaces of the fabrics, When thus operatedsingle sewing threadwhich binds thefabrics together may easily beunderstood from an inspection of Fig. 12. This particular stitching isformed by the operation of a particular type of sewing machine. It is tobe understoodhowever, that I do not wish to limit my invention to anyparticular kind of machine, and hence to any particular kind {of stitch,but my invention comprises the use of any machine and any form of stitchfor securing the suitably folded edge portions of fabrics in spacedrelation.

For instance, the two folders may be oppositely disposed insubstantially the same plane, their discharge ends suitably separated toguide the fabric folds into the path of operation of the needle of afagot machine; in this case the fabrics are'folded as previouslydescribed and secured in separated relation by a fagot stitch.

' My improved fabric connection is suitable for use many art in which itis desired to sew fabrics together With their edges separated. It istherefore useful in'the manufacture of umbrellas or parasols, especiallysuch as have a border portion secured to the main central portion butslightly spaced therefrom. Heretofore it was necessary in themanufacture of such para'sols to fold over and stitcha hem'on each pieceof fabric and thereafter to stitch the two hemmed edges together bya'loose stitch. It will be seen that my connection accomplishes thesameresult in one operation, necessitating the use of only one machineand one conproximately three times as much thread. The time consumed inmaking my fabric connection is also, as will be apparent, veryconsiderably less than that needed formerly for connecting fabricstogether in spaced relation. My connnection is furthermore, stronger andneater in appearance than former similar connections.

1. The combination of a plurality of fabrics, their edge-portions beingsubstantially parallel to and spaced from each other and theedge-portion of at least one of said fabrics comprising a plurality oflayers of fabric, and a single thread piercing said edge portions andconstituting the means both to secure said fabrics together and to holdsaid layers in place, said thread passing through a single longitudinalseries of needle perforations through the edge of each fabric.

2. The combination of a plurality of fabrics, their edge portions beingsubstantially parallel to and spaced from each other and the edgeportion of each comprising three folds, two of which face in onedirection, the third facing in the opposite direction, and stitchingpiercing said edge portions and serving both to secure said fabricstogether and to hold said folds in place.

3. The combination of a plurality of fabric portions, their contiguousmarginal edges being spaced apart and inturned to form folds located onthe under side of each fabric portion and a single thread holding saidparallel and spaced from each other and the edge portion of eachcomprising three folds, two of which face in one direction, the thirdfacing in the opposite direction and the edges of two of said foldsforming the edge of each fabric and stitching piercing said edgeportions and serving both to secure said fabrics together and to holdsaid folds in place.

5. The combination of a plurality of fabrics, their edge portions beingsubstantially parallel to and spaced from each other and the edgeportion of each being inturned to form folds located on one side of thefabric, the visible surfaces of the folds being the same as the surfaceof that side of the fabric on which said folds are located, andstitching piercing said edge portions and securing said fabricstogether.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
